Substantial evidence shows that childhood maltreatment and sleep duration play important roles in the development of suicide. However, the role of sleep duration in the relationship between childhood maltreatment and suicide behaviors, including suicide ideation, plan and attempt, was not fully understood. This study investigated the association among childhood maltreatment, sleep duration and suicide behaviors. 13,454 students from a polytechnic college in Shenzhen of China participated in this cross-sectional study. Multivariate logistic regression model was established to analyze the relationship among childhood maltreatment, sleep duration and suicide behaviors. The most reported subtype of childhood maltreatment was physical neglect, which were reported by 41.57 % of males, 28.59 % of females. The positive association of physical abuse with suicide behaviors was observed. In females, emotional abuse and neglect were positively associated with suicide behaviors. In addition, almost all childhood maltreatment was significantly associated to decreased sleep duration. Moreover, compared to the sleep duration <6 h group, sleep duration was inversely associated to suicide behaviors. Childhood maltreatment was positively associated with suicide ideation, plan and attempt in Chinese young adults. Meanwhile, childhood maltreatment was negatively associated with sleep duration, which were negatively associated with suicide ideation, plan and attempt. • Childhood maltreatment were significantly associated with suicide ideation, plan and attempt in the young Chinese people. • Sleep duration were inversely associated to suicide ideation, plan and attempt. • Physical abuse, sexual abuse, physical neglect and emotional neglect were all significantly associated to decreased sleep duration.

Test anxiety symptoms were measured by using the Test Anxiety Scale. Descriptive statistics and multivariate logistic regression were used to assess test anxiety and risk factors.Results: In total, 7047 students aged 10 to 19 were included for this survey. The prevalence of test anxiety was found to be 46.7 %. In multivariate analysis, gender, age, frequency of feeling lonely, parents' marital status, family functioning, emotional abuse, physical abuse, sexual abuse, academic performance level, relationship with classmates, school bullying and Internet addiction were positive related to test anxiety.Limitations: This cross-sectional design limits the establishment of causal relationships.
